Here is a Grand Slam Pinball game for sale. It was made by Gottlieb in 1972. This has a baseball theme and you can win free games on score and on runs. It features a roto target, and a eject hole for each base. When the bases are loaded, the thumper bumpers are worth 1000 points instead of 100 points. A home run gives you 5000 points. This is one of Gottlieb’s famous wedgehead pinball machines. You can get the game to take quarters or be on free play.
